COLTEn-'i-AsTlarxuNel SPECIFICATION forming part of Letters Patent No.340,506, dated April 20, 1886.

Application filed July 29, 1885. Serial No. 172,950. (No model.)

T0 all whom t may concern:

Be it known that l, HENRY HEIDACKER, a citizen of the United States,residing at Metropolis City, -in the county of Massac and State ofIllinois, have invented certain new and useful Improvements inColter-Fastenings, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to plow-colters, and has for its object theprovision of means whereby a colter may be secured to a plow-beam insuch a manner that a strong rearward pressure upon the lower portion ofthe colter,when the plow is in service, shall not displace it or splitor break the plow-beam.

The invention consists in a plate provided upon its face with suitableribs that embrace the edges of the colter-shank, securing-bolts, andlaterally-projecting lugs that engage the 'upper and lower surfaces ofthe plow-beam, substantially as hereinafter more fully described, andpointed out in the claim.

In the drawings, Figure l represents a portion of a plow-beam providedwith my-invention. Fig. 2 is a top plan view thereof. Fig. 3 representsa transversesection of the plowbeam, taken on the line x w of Fig. 2.Fig. 4 represents a detail view of the colter-securing plate detachedfrom the plow-beam. Fig. 5 represents an end view of the plate shown inFig. 4.

Similar letters of reference in the several drawings denote similarparts.

Referring to the drawings, A designates the plow-beam, B the colter, andC a plate by which the colter is secured to the beam. The shank b of thecolter B is provided with parallel edges b', that bear, when said colteris in positionupon a plow-beam,against ribs c, cast or otherwise securedto the outer face of the plate O. I preferably form one end of each ofthe ribs c of greater width than the opposite ends, and place such widerend upon opposite Aedges of the plate, (see Figs. 1 and 4,) the purposeof which construction will presently be explained.

c c designate apertures in the plate C, at diagonally-opposite cornersthereof, for the o passage of bolts m, whereby the plate is secured tothe plow-beam. c2 c2 designate similar apertures in said plate, at aboutthe center thereof, for the passage of bolts mwhich, in connection witha clip, kD, hold the colter in position against the face of the platebetween the ribs c c. y

O C designate lugs projecting from the upper and lower edges of theplate at diagonallyopposite corners thereof, as shown.

D designates a clip, which passes from one to the other of the ribs c,and is secured against the face of the colter-shank by bolts a and nutsa.

Thecolter B may be adjusted up or down between the ribs c c, and held atany desired height by means of the clip D and bolts a.

By reference to Fig. l it will be seen that the lugs O are placed atdiagonally-opposite corners of the plate O-one'upon the upper forwardedge of said plate in front of the coltershank, and the other upon thelower rear corner of the plate in rear of said colter-shank-and thatsaid lugs extend upon the upper and lower surfaces, respectively, oftheplow-beam.

By the abovedescribed construction the -plate O is prevented fromturningin the direction indicated by the arrows g by force applied inthe'direction of the arrow o to the lower forward edge of the colter,whereby all danger of breakage or splitting of the beam by plate Cturning on the bolts a is obviated, the lugs C' holding the plate fromturning, thereby relieving the boltsa from lateral strain, and keepingthe colter in its proper position.

The above description has been made in view of the application of mydevice to a wooden plow-beam; but it will be understood that said plateO may be attached to a metal plow-beam with equally good resnlts,inwhich case the bolts m may be dispensed with and clips used in lieuthereof to hold the plate in proper position.

To further strengthen the device I preferably make the ribs c c wider atthe ends which are adjacent to the lugs C', thereby increasing thestrength of the ribs at points subjected to the greatest strain from thecolter.

Modilications of the within-described improvements may be made withoutdeparting from the spirit or sacrificing the advantages IOO of myinvention-as, for instance, the ribs c c allel and re-enforced ribs, anda, clip which may be ent away at the center,and thus admit overhangssaid parallel ribs, said plate and the clip D to bear against the outersurface of clip having perforations tol receive the securr 5 acolter-shank, Whose thickness is less than ing-bolts, whereby the clipis scoured to the 5 the ribs. plate and the plate to the beam, as andfor the Vhat I claim ispurpose set forth.
